Episode notes
From $700 To Door Knocking At 42
- Kirt came to the U.S. from South Africa with $700 and built a career in corporate America before starting a roofing business at 42.
- He left an executive VP role and willingly did door knocking to learn the business and earn credibility.
Sell Before You Systemize
- Lead with sales first and build systems after you validate demand with revenue.
- Hire people who have skills you lack instead of building perfect processes before selling.
Costly Lesson From A High-Rise Job
- Kirt expanded into commercial roofing too quickly and botched a high-rise condo job due to inexperience.
- The seam mistake cost them hundreds of thousands and taught them to 'stay in your lane' until you're ready.
